British Airways has been implementing a comprehensive range of Honeywell safety systems across its B777 and A320 fleets since 2010, including IntuVue 3-D Weather Radar, which will help save on maintenance costs by enabling pilots to detect damaging weather earlier and avoid it; SmartRunway, which uses Honeywell s Enhanced Ground Proximity Warning System (EGPWS) database to reduce the risk of runway incursions by warning the crew if any aspect of taxi or takeoff is not correctly configured; and Traffic Alert and Collision Avoidance System (TCAS) with SmartTraffic, which provides pilots with real-time awareness of surrounding traffic to maximize the use of optimal flight levels.
These include: human error by air traffic control and pilot; coordination failure like late or non-receipt of flight level change; radar failure; failure to get message properly leading to pilot climbing or descending to a wrong level; a trainee ATC working and his or her instructor getting late in correcting a mistake and "heavy traffic leading to stress and fatigue".
Seven occupants of the A330-300, operated by Qantas Airways, were injured as it met turbulence at flight level 380 while approaching the northern coast of Malaysia.
